MACHINE FOR CUTTING WOODEN HOOPS.

SPECIFICATION forming part of Letters Patent No. 263,044, dated August22, 1882. Application filed May 17, less. (No model.)

To all whom it may concern:

Be it known that I, I )AVID F. HOLSTON, of Defiance, in the county ofDefiance and State of Ohio, have invented new and useful Improvements inMachines for Cutting Veneer- Hoops; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to theaccompanying drawings, which form a part of thisspecification.

The nature of this invention relates to certain new and usefulimprovements in the construction and operation of machines which aredesigned to cut hoops from thin veneers in contradistinction to thosemachines which out such hoops from the edge of planks thethicknessofwhich determines the width ofthe hoops.

The invention consists in the peculiar construction and combination ofparts and their operation, as more fully hereinafter described.

Figure l is a front elevation of my improved machine. Fig.2 is an endelevation, showing the feed mechanism. Fig. 3 is a sectional elevationof the opposite end. 0

In the accompanying drawings, Arepresents the frame of the machine whichcarries and supports the working mechanism.

B is the bed, in front of which is the roll 0, suitably journaled ateach end in the frame.

Another roll, D, similarlyjournaled and projecting slightly above theplane of the bed and forming one of a pair of feed-rolls, is employed.The fellow, E, of this roll is journaled in vertical sliding boxes F,which are supported by the vertical standards G.

H is a lever, one end of which is pivotally secured to one part of thestandard,as shown, and this lever is provided with a slidingcounterbalance-weight, I. The ofice performed by this lever and itsattachments is to afford the necessary pressure on the upper one of thefeed-rolls and allow different thicknesses of veneers to be operatedupon, as may be desired, to produce" thicker or thinner hoops.

J is the knife or cutter, which has a reciprocating vertical movement,being actuated thereto by the cam K, which is secured to the main shaftL; and M is a pitman which connects said cam with the sash or gate T,which carries said knife or cutter.

, N is a pressure-foot, adapted in any of the side is provided with asuitable. pawl, (not shown,) which is designed to engage with the teethof the ratchet-wheel S, which is secured to one end of the lowerfeed-roll. By this lattor-described mechanism the feed is regulated atwill.

A stop, 0, is secured to the pressure-foot arm to prevent the cut ofi'hoop from following the upward stroke of the knife and compel it to dropafter the knife has passed upward sufficiently far to allow such action.

I am aware that it is not new to combine an intermittent feedingmechanism with a reciprocating cutter in apaper-cuttingniachinc, and Ido not claim such invention.

What I claim is 1. In a machine for cutting hoops from ve- .neers, thecombination, with the supportingframe and the reciprocating knife andpressurefoot, of the roll D, the vertically-adjustable roll E, theratchet-wheel. S, the crank R,

the adjustable pitman Q, the lever P, and the cam O, as and for thepurpose specified.

2. In a machine for cutting hoops from veneers, the combination, withthe supportingframe and the knife J and feeding-rolls D E, of the gateF, pitman M, and cam K, for imparting a reciprocating movement to theknife, the cam 0,1ever P, rod Q, crank R, and ratchetwheel S, forimparting an intermittent rotary movement to the roll E, and thepressure-foot N, and. the stop 0, all constructed and operatingsubstantially as and for the purpose specified.

ln witness that I claim the above invention, I have hereunto set my handthis 1st day of May, A. D. 1882.

DAVID F. HOLSTON.
